I'm a few years away from the official retirement age but if fortune smiles I might be able to step away a little sooner than that. I've always been interested in investments (even as a teen) and have read way too many books on the subject. Still do. Was lucky enough to make my investment mistake very early when the tuition didn't cost me very much - I bought a pink sheet stock from a boiler room operator who cold-called me! He promised me it would go way up but somehow it didn't turn out that way.
My personal investment style has always been overly conservative, having grown up poor. But it's not ridiculously so - 50%/35%/15%. Could have done better over the years being more aggressive, but that's history now.
I'm a fan of the low-cost index fund / asset allocation / rebalancing methodology.
Currently I spend time beating many different retirement calculators to a pulp
evaluating our situation and waiting for the light to turn green, so to speak.
